Der unbegrenzte Himmelsraum
In Romanticism, the limitless space of the sky symbolises the longing for freedom in a time of upheaval and political and social repression. At the same time, however, the sky opens up a great emotional space in painting and appears as a value in its own right: in its gradations and variations of colour, as well as in the amorphous forms of the clouds, painters are also experimenting with a freedom of art that leads to abstraction in 20th century art.
